An individual's sense of themselves as a "STEM person" is largely formed through recognition feedback. Unfortunately, for many minoritized individuals who engage in STEM (science, technology, engineering, and mathematics) in formal and informal spaces, this recognition often adheres to long-standing exclusionary expectations of what STEM participation entails and institutionalized stereotypes of what it means to be a STEM person. However, caregivers, who necessarily share cultural backgrounds, norms, and values with their children, can play an important role in recognizing their children's interest and inclination towards STEM in ways that support children's authoring of their STEM identity in the face of these marginalizing discourses. To explore this idea, we conducted phenomenological interviews with STEM students attending a Hispanic-serving university, examining the nature of STEM-related conversations these students had with their parents during childhood. Participant recollections provide evidence of conversational content, contexts, and structures that supported their identification with STEM even when faced with marginalizing experiences. We found that though this phenomenon was recounted across parent profiles, participant narratives also reflected differences in conversation content, context, and structure based on factors associated with STEM
